Certificate of analysis
Material name, batch reference, specification, test items, results, and review date.

Evidence organized
around the actual batch.
A dedicated testing center for qualified B2B buyers: locate a batch reference, understand the analytical file set, and request the matching documents.
01 / Batch reference
Start with the code on the label or document.
Public document libraries can separate a file from its commercial context. Qyonz Peptide Lab verifies the batch or COA reference first, then shares the applicable analytical record with a qualified buyer.
Have a real batch or COA reference?
Send the exact code with the material name and quotation reference. We will confirm whether a matching file is available before sharing it.
Request batch-file review →02 / Analytical file set
Four evidence layers, one traceable reference.
File availability depends on the material, batch, destination, and requested program. Documentation is never presented as proof of clinical suitability.
Purity profile
Chromatographic profile used to assess relative purity against the applicable analytical method.
Request file review →Identity support
Mass-spectrometry evidence used to support molecular identity and expected mass.
Request file review →Safety information
Research handling, storage, hazard, transport, and disposal information when applicable.
Request file review →03 / Representative dossier anatomy
One batch reference across every file.
A reviewable dossier should let a buyer cross-check the product identity, batch reference, specification, results, analytical evidence, and release context without mixing unrelated files.
- Material name and internal catalog reference
- Unique batch or COA reference
- Specification, test result, method, and review date
- Chromatogram and identity evidence alignment

04 / Testing workflow
How verification moves from material to file.
- 01
Material & batch identification
The requested compound, format, and batch reference are matched.
- 02
Method review
Applicable identity, purity, and specification methods are checked.
- 03
Result alignment
The COA values are reviewed against chromatographic and identity evidence.
- 04
Buyer verification
The matching file set is shared within the qualified B2B quotation process.
05 / Independent analysis
Third-party testing can be coordinated by scope.
For defined programs, Qyonz Peptide Lab can coordinate independent laboratory analysis or buyer sample selection. Laboratory, method, sample custody, cost, and acceptance criteria must be agreed before testing begins.
